Summer: safety measures for pregnant rabbits to spend the summer
In the hot summer, measures should be taken to ensure that pregnant rabbits spend the summer safely.
First, pay attention to heat prevention and cooling. The suitable temperature for pregnant rabbits is 14-16 ℃. In summer, we should do a good job in preventing heat and cooling to prevent heat stress, resulting in premature delivery, miscarriage or stillbirth of pregnant rabbits. Keep the rabbit house cool and well ventilated, and the rabbit house will build an Arbor.
Second, adjust the feed in time. Heat often results in a decrease in food intake of pregnant rabbits. It is necessary to adjust the feed in time, increase the proportion of protein and energy feed, feed more green succulent feed, and ensure to meet the nutritional needs of pregnant rabbits in the case of reduced feed intake.
Third, adjust the feeding time. It is hot at noon in summer, and pregnant rabbits often lose their appetite. Most of the feed should be fed in the morning and evening to reduce daytime intake and activity. Feed early for breakfast, feed late at night, add forage at midnight, provide enough clean drinking water at noon, and feed more green fresh grass.

Fifth, do a good job in hygiene and epidemic prevention. Keep the rabbit cage dry and hygienic, frequently sweep rabbit dung, prevent the accumulation of rabbit dung, urine and sewage, and wash and disinfect the sink, food trough and utensils once a day.
Sixth, repelling mosquitoes and flies. Mosquitoes and flies breed in summer, germs are easy to reproduce, so it is necessary to do a good job of repelling mosquitoes and flies in the rabbit house. Order mosquito-repellent incense or crystal trichlorfon wrapped with gauze in the rabbit house at night. Conditional screen doors and windows can be made to ensure smooth ventilation of the rabbit house and prevent mosquitoes and flies from flying into the rabbit house to bite the rabbit.

Fish species released in autumn and cultivated in autumn to keep them alive
Strengthening the cultivation of fish species in autumn is the key to improve the survival rate of overwintering fish species. Improve the environment before the release of fish species, release half of the original pond water, and then add new water. 150 kg fermented manure was applied per mu pond, once every 9 days, for a total of 3-5 times. Appropriate topdressing of chemical fertilizers based on nitrogen and phosphorus, generally 1.5-2.5 kg of urea and 3-5 kg of superphosphate per mu of pond, about once every 7 days. Add fresh water after each fertilization to keep the transparency of the pool water at 20-30 cm. Use 10-15 kg of quicklime per mu of water every half a month
